CONDENSER.

Specification of Letters Fatent.

Patented July 24, 1906.

Application filed Iuly l, 1904. Serial No. 215,041.

To all whom it may concern:

Be it known that I, FRANZ ENGLErTNEE, civil engineer, a subject of the Emperor of Austria-Hungary, and a resident of Schwertberg, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Condensers and Feed-Water Heaters for Boiler Feed-Water and other Purposes, of which the following is a specification.

My invention relates to certain new and useful improvements in condensers and feedwater heaters for boiler feed-water and other purposes, and has for its object to improve the said mechanism in such a manner that the whole quantity of steam passing is in the same degree cooled down and utilized.

A further object of my said invention is to hold the water in every cross-section of the apparatus on the outside' and inside of the steam-pipes at one and the same temperature.

I obtain the said objects by the mechanism hereinafter described, and illustrated in the annexed drawings, in which- Figure 1 shows an apparatus in longitudinal section which is more especially suited for smaller quantities of steam. Fig. 2 is also a longitudinal section of an apparatus especially suited for larger quantities of steam. Fig. 3 shows further details.

My invention as shown in Fig. 1 consists of two concentrical metal tubes 1 2, with an interspace of a few millimeters between them, which tubes are provided at their lower ends with joint-pieces 3 4, fastened to them by hard soldering. Within the tube 2 a loose iron tube 5, with stop er 6, is provided, which tube has arranged s its at its top and bottom and serves to guide the inner stream of water. The said modification of my invention as shown in Fig. 1 possesses a jacket 7 ,with stuffing-box at the lower-end, a dome 8 with steamort socket 9, a lid 10 on top of the latter, a rther socket 11, screwed into the piece 4 as eXit for the condensation-water, a gas-pipe 12, projecting into the piece 4, two T-iron pieces 13 14 for the distribution or collection of the water, and a discharging device 15.

When working the apparatus, the eX- y haust-steam enters the port-socket 9, passes through the interspace between the two metal pipes 1 2and then leaves the apparatus through the socket 11 as cooled water. The feed-water is conducted in a contrary direction through the inlet 13, where it separates into two streams, one passing up the space between the casing 7 and tube 1, while the other stream enters the pipe 12 and passes up the ap aratus in the space between the plugged tule 5 and the tube 2. The outer stream of water leaves the casing 7 by the socket 21, while the inner stream passes through the top slots 18 of pipe 5 into the pipe 22, both streams then making their exit at the outlet in the pipe 14. The object of the pipe 5 hereby is to prevent the formation of a dead nucleus, which, as is well known from practice, would otherwise form because of the comparativelylarge diameter of pipe 2.

Provisions have been made for a thorough cleaning, as the apparatus can be entirely taken to pieces.

In the modification of my invention shown in Fig. 2 a number of double pipes are united in one jacket for the purpose of condensing a larger quantity of steam. Here the steampipes 1 and 2 are rolled in at the upper wall 16 and 17; but in the lower they rest in stuifing-boxes and are tightened by the same, The construction of the stufling-boxes is shown in Fig. 3, but may as well be constructed in any other suitable way. Preferably said stuffing-boxes are constructed exactly like those of ship-condensers. The working process in the second modification, as shown in Fig. 2, is similar to that aforedescribed and consists in the exhaust-steam entering at 9, passing through the interspaces between the pipes l and 2, and leaving the apparatus as water at 11. The cold water is divided by the T-piece 13 into two streams, which then pass in a counter-stream along the steampipes on the outside and inside and are afterward united again by the T-piece 14.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. Condenser and feed water-heater for boiler feed-water and other purposes comprising in combination elements consisting of two concentric pipes 1, 2 having at their lower ends adjoint pieces 3, 4, a loose tube 5 with stopper 6 within the said element bearing slits at its top and bottom, a jacket 7 surrounding the said element with stuliing-box at the lower end, a dome 10 with steam-port socketQ and lid 10 on top of same, substantially as described and shown and for the purpose set forth.

screwed into thepiece 4, a gas-pipe 12 prol j ecting into the latter and two T-iron pieces 13 and 14 for the distribution or collection of the water, substantially as described and shown and for the purpose set forth.

In witness whereof I have hereunto signed my name, this 19th day of May, 19947 inthe presence of two subscribing witnesses.
